by the dotted line or level F. All excess gasoline delivered to the tank during the lillingj operation isV returned through the pipe Y Y Y Generally speaking, my invention consists in providing means for controlling the dise charge of gasoline from the tank to coin-V mence and end at a selected one of a series of predetermined discharge levels located below the gasoline level F and designated respectively by reference charac-ters F', F2,

F3, F4 and F5. These discharge levels are uniformly spaced 'apart With the upper level F located beloW'the gasoline level F a distance exactly equaly to' ythe distance intervening between adjacent discharge levels. Prefleraloly the spacing of` the various levels re-V ferred to is such that When thegasoline is dispensed from the tankin successive discharging operations, occurring at the diiferent discharge levels in the order offtheir arrangement, beginning With the level F', the

quantity of gasoline Vreleased from the tank at each v( lischarge Will be exactly one gallon. As previously pointed out, discharge fromV the tank may be controlled to commence and end at any selected .one of the several ,discharge :levels-and hence if it iskdes'ired to dispense three gallons from the tank Vin the initial discharge, the latter will be caused to occur at the discharge level F3, It will thus be apparent that when the tank is filled to bei discharged iny predeterminedv quantities -ranging from one to five gallons.

its full 7capacity,the contents thereof may L In order to'controldiscliarge from the tankto take place at the differentlevels p reyviously :referred to.-I provide the tank with a series of-outlets designated .5, 5a, 5b, cfand 51. yThese outlets-for the tank are in the form-of ,casiiigs shaped as shown in Fig. v2 and positioned in the ta-nk one above the other.v Each casing is provided with a top `opening ,6 and .av bushing 7 threadedly engaged in said Yopening and having its lower `end'shapedfto forma valve seat 8 normally engaged by a valve 9 Vwhich serves to close the opening `to disrupt communication between ,the .interior of the casing and -t he tank A. The upper extremities of the sev'- eralbushings Yeare formed' to presentknife edges "fflL projecting above the ktop Wall of the ycasing and'contained respectively in the Identical means are provided for .selecherein slnnvn, such ineens consist of a lever l5 mounted on an intern'iediate pivotlG and ttorined with a forked extremity 17 straddlinn' the *alve stein l) and resting on the eroi-s pin lll. lhe remaining end of each lever is eonneeted lanv a llexiblo strand or Wire l5 to one ol a series ot kevs lll. Each key is in the` torni o lf a lever haviugl` one extremity pivoled upon a shalt. i0 and the other eX- tronlitv equippei'l with a linger pieee 2l, the aetnating wires heine' eonneeted to the levers at any suitable point intermediate the shattan'd linger piece. lt will thus he apparent that. upon depressing any selected one olf said keys the valve connected therewith will he moved array troni ,its seat to drain the tank down lo the level roiin'idinn` with the knile edge i ot the hushing; associated with the open valve. lit is necessary that seine means he provided ttor retaining: the keys in depressed posiion and 'tor this. purpose. eaeli key is passed llu'oueh a slot 22 torlned in the shell ill supporliing the tank n.. A t its loiver end. eaeh slot is provided with a lateral elite ision in which the kev. oinralinn` in said slot is adapted lo he secured to hold the kev in depressed position. ln order to provide 4tor the lateral movement ol the keys ueeessarv to engage the saine in the extensions 22" oit the said slots. the ends olI the kevs mounted on the shalt Q0 are provided with rrlativehv large oifieuingrs reeeivine the shalt theretlnougrh so that the keys are eapalile oil a sliaht lateral movement with revneet lo the shaft.

lith reference to the mounting ot the outlet easinggs in the tank A. it will he noted that the several easinns are connected together hv nipples Qflwith the easing 5" restino: direetlv on the hottotn ot the tank and eoiineeted throue'h an elhow Q5 to the flexible deliver)r hose QG. Preilerahlv. a eut-oil 97 oii the. usual type is interposed in thel connection between the rlhow Q5 and the deliverv hose 2G. The upper outlet easing' 5 is eonneeted hv a vertiral pipe 2S to one extremity ol a U-shaped eoupline; Q9 strafldlinfv; the upper end oli' the tank. A guide tuhe 30. disposed exteriorlv oil4 the tank A. extends from the remainiinjr extremity ot Coupling 29 to a point adjacent the kevs 19. The several Wires 18 extend from the levers l5 through nipples ill. pipe QS and guide tube SO to their respective kevs. Preferably. easings 5, 5". 5b. and are provided. as shown in Fig. 2. with guide staples 3l through Whieh are earried the Wires 19 'troni the easingrs positioned therelielow. Tn this Wav, fouling of the Wires during seleetive operation oi. the

`valves is prevented. Il desired. each Wire 1S inavihe enclosed in an .individual guide tuhe 1S entendingt. as shown in Fifi. 2. troni the top easing; 5 to the lower end of the main guide tube 30. i

For convenience of operation, keys 19 are consecutively nnl'nhered .from l to 5, as indicated in Fig. 5, the key l being;l connected to the valve oiiierating lever ol easing; 5; the key 2 to the valve operating;r lever ol easing 5", and so o.n

ln explainingT the complete operation, We will assume that tank il. is (charged to its :full eapneiity. :is represented by dotted line F, and that it is' desired to dispense one gallon oit `gasoline. This is :n.eoinplished by depressing and engaging kegY .l in the olli-:et 22 ol slot wherein7 the valve l) olf easing 5 is withdrawn :lroin engagement with its seat 8, thereby placing the interior oit the easing i i. eoiunniniealion with the tank. The gasol ne will non' lion' Atroni the tank through C isine 5 and nipples Qi lo the delivery hose 2l until the level of gasoline in Athe tank is lowered to the point li" at which time further 'diseharge 'trein the tank will automatieallv terminate. liv suhffsequently selecting anv one ol the remainingl keys.y further predetermined quantities ot gasoline may he disehargled `troni the tank ra nniiip; :from one to tour gallons. ll. when the tank is filled lo its Carnielli. ilA is desired lo fliseharge live gallons or prfnftieallj.' the `lull contents of the tank, this is accomplished h v depressing the key eouneeted to the valve eontained in the outlet easing 5d. lt is thus apparent, that hy selective operation oi the various keys, the eontents of the tank nnrv loe dispensed at lwill in ana7 predetermined quantity. ranging 'troni one gallon to :unv multiple thereof Within the capacit;T of the tank. Y

In order to seal the ffalves 9 against leakaggje when in elosed position, I may provide the pipe E28 with an openingr Q8 loeated a predetermined .distance aliove the easing 5. Tn this modified structure. it Will he apparent that when the tank is filled to its eaparity.` the level of the gasoline will he in the plane oit said openingr as a certain `pereentag'e of the gasoline will flow thru the opening to till the nipples 241 and the several mlve easings. It. will he understood, in this connection, that the quantity of Igasoline oonl'ained in the nipples @il and in theA valve easings added to the quantity of gasoline eontained in the tank between the easing 5 and the opening- 2r. will` equal exactly one gallon.

llVhile in the foregoing I have described what I now eonsider to he the preferred einhodin'ient of the invention7 it will be apparent` that the same results could he accomplished hv other means such for example as the provision of a` single outlet adjustahle Within and .in reference to the tank to dispose the receiving end ol the outlet at anv seleel'ed one ot the diseharpge levels F'. F, F3, F4 or F5. It will also he understood that. various other Changes in the construetion and arrangement of parts may `he resorted to Within the scope of the appended claims without departing from the spirit of the invention. j

What I claim is:

1. A dispensing tank equipped with a series of vertically` spaced outlets located therein, each of said outlets comprising a casing having an opening in its top wall for placing the interior of Ythe casing in communication with the interior of the tank, a bushing fitted in said openingand having its upper extremity shaped to provide a knife edge surrounding and projecting above the opening, a. valve normally seated against the lower end of said bushing to disrupt' communication between the tank and the casing,

and means for moving the valve away from said bushing.

2.- A dispensing'tank equipped with a series of vertically spaced outlets, each outlet consisting of a casing having an opening formed in its top wall and a valve normally closing said opening, nipples connecting the several c asings together, a delivery pipeleading from the lowermost casing, a guide tube connected with the uppermost casing, a plurality of actuating levers, and actuating wires connected between said levers and saidV valves and passing through the guide tube.

3. A dispensing tank equipped with a series of vertically spaced outlets, each outlet consisting of a casing having an opening formed in its top wall, a valve normally closing said opening and formed with a depend- `ing valve stem having a pin passing transversely therethrough, a guide receiving the lower end of said stem, a lever pivotally mounted within said casing and terminating at one end in a fork straddlin the valve stem and overlying said pin, nipples connectingthe vseveral casings together, a delivery pipe leading from the lowermost 'casing and means for independently operating said levers to move the valves to open position.l

4l. A dispensing tank equipped with a series of vertically'spaced outlets, each outlet consisting of a casing having an opening formed in its top wall, a bushing secured iny the forked end of the lever is depressed itV engages the pin to move the valve away from its seat, an operating element connected to the remaining end of the lever and a delivery pipe connected to all of said casings.
